-## Data
-
-`MDBook::new(root)` parses CLI args and `book.toml` to create:
-
-- app config settings
-- `Book` for each language
-
-Each `Book` is given their config setting with their source- and destination
-paths.
-
-The renderer can then render each book.
-
-To render the TOC, renderer gets a Vec<TocItem> from summary parser.
-
-The renderer walks through the Vec. It can match content kinds in an enum and
-this way knows whether to render:
-
-- front- back- or mainmatter
-- spacer elements (vertical space in TOC but no chapter output)
-- insert chapters (no TOC link, but the chapter is part of the reading sequence)
-
-![book data](assets/bookdata.png)
-
-### Renderer
-
-Takes a book, which knows:
-
-- metadata
-- toc with chapters
-- config for paths
-- template assets (`template_path`)
-
-For generating pages:
-
-Book metadata, `BookMetadata` (title, author, publisher, etc.). Just recognize
-those properties which can be easily anticipated.
-
-If Renderer needs more specific data, it can be supplied in `book.toml`. It's
-the Renderer's job to open that and parse it out.
-
-Chapters are represented in a `Vec<TocItem>`, each item has the chapter content
-as payload.
-
-If the user wants to store attributes that are not anticipated with structs,
-they can go in a hashmap with string keys, let them be accessible from the
-templates with helpers.
-
-For generating output:
-
-- template assets, `template-path`, renderer does whatever it wants with it
-- config (root, dest, etc. folders)
-
-Renderer is seleceted by CLI or default (html). Each book is passed to this
-renderer.
-
-### Config
-
-Takes data from:
-
-- CLI args
-- book.toml
-
-## Structs
-
-### Reorganized
-
-![structs reorganized](assets/structs-reorganized.png)
-
-### Currently

-![structs](assets/structs.png)
-
-## Notes
-
-Take config paths for as many things as possible. Let the user organize their
-project folder differently, or allow `mdbook` to function in existing projects
-with already established folders.
-
-Add config path for `SUMMARY.md`. Default is good to be in `src/`, it allows
-chapter links to work when reading the file on Github.
-
-The init command should copy the assets folder by default, it is better to make
-this choice for new users.
-
-The specific assets (CSS, templates, etc.) are closely coupled with the book
-content when the user is writing it. If the templates change when mdbook
-develops, this changes the output in a way the user doesn't expect, maybe even
-breaking their book.

+They were indeed a queer-looking party that assembled on the bank—the birds with
+draggled feathers, the animals with their fur clinging close to them, and all
+dripping wet, cross, and uncomfortable.
+
+The first question of course was, how to get dry again: they had a consultation
+about this, and after a few minutes it seemed quite natural to Alice to find
+herself talking familiarly with them, as if she had known them all her life.
+Indeed, she had quite a long argument with the Lory, who at last turned sulky,
+and would only say, "I am older than you, and must know better;" and this Alice
+would not allow, without knowing how old it was, and as the Lory positively
+refused to tell its age, there was no more to be said.

+Alice was beginning to get very tired of sitting by her sister on the bank, and
+of having nothing to do: once or twice she had peeped into the book her sister
+was reading, but it had no pictures or conversations in it, "and what is the use
+of a book," thought Alice, "without pictures or conversations?"
+
+So she was considering in her own mind, (as well as she could, for the hot day
+made her feel very sleepy and stupid,) whether the pleasure of making a
+daisy-chain would be worth the trouble of getting up and picking the daisies,
+when suddenly a white rabbit with pink eyes ran close by her.

+at her feet, they seemed to be almost out of sight, they were getting so far
+off). "Oh, my poor little feet, I wonder who will put on your shoes and

+Christmas."

+And she went on planning to herself how she would manage it. "They must go by

+Ils formaient une assemblée bien grotesque ces êtres singuliers réunis sur le
+bord de la mare ; les uns avaient leurs plumes tout en désordre, les autres le
+poil plaqué contre le corps. Tous étaient trempés, de mauvaise humeur, et fort
+mal à l’aise.
+
+« Comment faire pour nous sécher ? » ce fut la première question, cela va sans
+dire. Au bout de quelques instants, il sembla tout naturel à Alice de causer
+familièrement avec ces animaux, comme si elle les connaissait depuis son
+berceau. Elle eut même une longue discussion avec le Lory, qui, à la fin, lui
+fit la mine et lui dit d’un air boudeur : « Je suis plus âgé que vous, et je
+dois par conséquent en savoir plus long. » Alice ne voulut pas accepter cette
+conclusion avant de savoir l’âge du Lory, et comme celui-ci refusa tout net de
+le lui dire, cela mit un terme au débat.

+Alice, assise auprès de sa sœur sur le gazon, commençait à s’ennuyer de rester
+là à ne rien faire ; une ou deux fois elle avait jeté les yeux sur le livre que
